What is a WebRTC Leak?

WebRTC (Web Real-Time Communication) is a technology that enables direct peer-to-peer communication in browsers for video calls, voice chat, and file sharing.

A WebRTC leak occurs when your real IP address is exposed through WebRTC, even when using a VPN. This happens because WebRTC can bypass VPN tunnels to establish direct connections.

Private IPs (like 192.168.x.x or 10.x.x.x) are generally not a concern as they're not routable on the internet. Public IPs exposed through WebRTC can reveal your real location if you're using a VPN.

How to Prevent WebRTC Leaks

Firefox: Go to about:config and set media.peerconnection.enabled to false

Chrome/Edge: Use an extension like "WebRTC Leak Prevent" or "uBlock Origin" with WebRTC blocking enabled

Brave: Go to Settings > Privacy > WebRTC IP Handling Policy and select "Disable non-proxied UDP"
